She settled herself back onto his cock, her pussy still twitching around it, and relaxed her bladder, releasing a stream of hot liquid onto the cock inside her. It built up inside her briefly, then found it's way out past her pussy lips and onto Stuart's crotch, who was groaning with the unusual pleasure, before finding it's way onto the flight couch, where the nano-systems in the fabric cleaned it up.
The pair resumed their fucking with even greater ardour, the kinkiness of the act firing the perverted side of their imaginations. Raising herself off his cock and turning to face him, Sara placed her feet either side of Stuart's waist and squatted over his cock, spreading her arse cheeks to give his cock access to her anus. It slid in with little effort, as it was well coated with their juices, and Sara was soon grunting with pleasure as the full length of Stuart's dick pistoned it's way up her back passage, her anus squelching as it clenched his shaft tightly.
As Stuart's cock exploded inside her, Sara squealed and spasmed with another orgasm and collapsed forward on his chest. As they lay recovering, Sara felt his cock soften slightly, then gasped as another stream of hot liquid began to splash against her insides, as Stuart began to give her a urine enema direct from his cock. The stream continued for what seemed an age, far longer than any (human) cock could ever have come for, filling Sara's anal passage with hot liquid. As Stuart's cock began to soften, the mixture of urine and come began to ooze out of her distended sphincter, again flooding Stuart's crotch and making use of the nano-cleaners.
The pair crammed into the probeship's small bathtub, and were soon coated in lather and once again screwing one another's brains out, the soapy slipperiness opening further options for sexplay, as Stuart discovered to his delight as he slid his cock in the delightfully slippery yet hot and tight groove between Sara's breasts, as she wrapped them around his cock, her tongue licking the head each time it came near enough. A short time later they were engaged in a form of 69, as Stuart's tongue probed Sara's freshly cleaned asshole, while she did the same to him in between sucking his shaven scrotum, his cock still gripped firmly between her luscious breasts.
Feeling the way Stuart's cock twitched as her tongue probed his anus, an idea popped into Sara's mind. She climbed out of the bath, and leading Stuart by the hand, returned to her quarters, where she extracted a double ended dildo from her storage compartment. About twelve inches long, and self lubricating, it was one of Sara's favourite toys, although she mainly used it with other women.
Sara lay on her back and spread her legs, inviting Stuart to return his cock to her pussy, where it fitted so nicely. He obliged in a flash, sliding his full length inside her, his pubic bone resting against her clit. Sara rubbed the length of the dildo firmly, causing its self-lubrication to take effect, then began to insert one end into her own anus. She then paused for a second, but the look in Stuart's eye told her to continue, and she slid the other end into his arse, eliciting a groan of pleasure from her new lover.
With the artificial phallus firmly inserted, and the real one well entrenched in its rightful place, every move that either of them made gave both of them a dual pleasure. After a few thrusts they found that standard missionary fucking was something of a "mission," and manoeuvred themselves into a sitting position, facing each other, with Sara's legs wrapped around Stuart's waist. In this position, the pair could bounce together or separately, and the dildo in their arses would be pressed up by the couch below them.
As they writhed and bounced, slowly approaching yet another climax, the sounds and smells of sex filled the air. As she felt her orgasm begin to build, Sara reached down behind herself and fingered a soft hidden button on the fake penis, causing it to twist and vibrate.
Both Sara and Stuart grunted with the extra sensations, and the pair of them began to thrust at each other with even greater enthusiasm, culminating their pleasure in a simultaneous climax, Sara's pussy clamping down on Stuarts cock as it pumped spurt after spurt of hot thick come into her burning love box, the buzzing phallus in their arses overloading their bodies somewhat, as screams of pleasure became choked gasps and grunts, as the two hot young spacefarers finally collapsed into a sated pile of sweaty limbs and heaving chests.
A few minutes later, as they began to recover, Sara smiled at Stuart and remembered something.
"Hi, I'm Sara."
